	Have you set up bridging on your Linux host?  You might need to
do so in order to get the kernel to sling the packets back and forth for
you.  Here's an article in the Linux Gazette relevant to the sort of
thing you want to do:

And here's the site for the SourceForge project working on getting
bridging up and running with 2.4 kernels and iptables.
